Clinical Trial Summary

A Randomized trial comparing two different timing of taking thyroxine in patients with Hypothyroidism during fasting the month of Ramadan.

Description:

To date there is debate regarding the best timing of L-thyroxine administration during Ramadan as sufficient evidence is lacking. This study aims to compare two-time points of levothyroxine intake during Ramadan focusing on change in TSH, satisfaction and compliance. A prospective, randomized, open label, multicenter Study. The first group will be will be instructed to take their L-thyroxin dose as per current guidlines at breaking of fast time (sunset) with sip of water then wait 30-60 minutes to consume Iftar meal. The second group (pre-Fajer prayer), patients are going to be instructed to take L-thyroxin dose immediately before start of fast, i.e. Alfajer (dawn) regardless of Suhoor time. The values of Thyroid stimulating hormone (TSH) will be measured two weeks before Ramadan, and 2-4 weeks after Ramadan for comparison.
